Add the base lease and any setup or use-case charges to the advertised capability price.
The product in view
Contiguity prices the base number lease at $9.99 monthly and the iMessage capability at $69.99 monthly. Their sum is $79.98 before possible setup fees or use-case surcharges. The separate $19.99 Unlimited subscription covers SMS, MMS and email; it is not the iMessage line price.
Before you choose
Confirm the eligible number, channel combination and current provisioning process for your application. Inspect incoming events and fallback behavior rather than assuming every channel shares identical semantics. The breadth may suit a developer choosing a general communications stack, but the final buying comparison should use the configured iMessage price and an agreed scope.
